‘There’s no bad blood between them, which means everything has been extremely amicable. Watching the way they interact, you would never know that they had split, as they are still extremely good friends. Unfortunately, they just fell out of love with each other.’

The source added that it was important for the couple to put up a united front for their children.

The couple – who have daughters Holly, 16, and Tilly, 14, and son Chester, 11 – announced their split in November in a statement that said: ‘I am very sad to say that Matthew and I have separated.

‘Our amazing children are our number one priority, above everything else so therefore we ask for as much space and respect from the media as possible while our family goes through this difficult time.’

After wishing everybody a happy Christmas, she went on: ‘I think it’s one of those days isn’t it?

‘Where, sometimes even if you’re in a huge group of people it’s quite possible to feel lonely or if you’ve lost someone you really care about, and this is your first Christmas without them, or if you couldn’t get home to your family.

‘It’s only a day, and if you are feeling terrible, cuddle up with a duvet, make yourself some food as that’s a nice act of self-love, and go watch some funny Christmas films.

‘Lots of love, and I’ll be back at some point on Instagram this week.’
